So I plan on buying a pax tomorrow and read that the warranty only covers products sold through official retailers. I'm probly gonna get it at a head shop and was wondering if there are actually any shop that are official retailers besides online sites. I also read that it doesn't cover any misuse of the product so if you were to send it back would they notice that it was used with weed instead of other herbal products. Anyone with actual experience please let me know. Thanks blades
